VALVE.

Application led February 8, 1924. Serial No. 691,407.

To all whom t may concem.

Be it known that I, HENRY Soon, a citizen of the United States, and resident of Shreveport, in theA parish of Caddo, in the State of Louisiana, have invented -certain new and useful Improvements in Valves, of which the following is a specification.

This invention relates to gate valves especially adapted for use in water mains and the like. Briefly stated an important object of this invention is to provide a water main valve having oppositely located valves adapted to cooperate with seats at opposite ends of the valve so as to positively stop the iow of water.

provide a valve wherein the pressure of the water assists the opening of the valve.

Also an important aim of this invention is to provide a valve of the character specified having novel means whereby the accumulation of sand and other solid particles are maintained at a low point, and the valve' is provided with means whereby the same may be cleaned out periodically without shutting olf the flow'of water.

' A further object is tov provide a valve which is of highl simplified construction, durable in use an cheap to manufacture;

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this application, and in 'which like numerals are employed to designate like parts throughout the same,

Figure 1 is a vertical sectional view through the valve.

Figure 2 is a detail longitudinal sectional view illustrating the guiding means for the valve.

Figure 3 is a group perspective illustrating `an adjusting member for the several valves. d

' Figure 4 is a lon itudinal sectional view through a modified orm of the invention.

Fi re 5 is a transverse sectional view on the llne 5-5 of Figure 4. A

Fi e 6 is a perspective of a connecting 4mem er illustrated a plied in Figure 4.

In the drawing w erein for the 'purpose3 of illustration is shown a preferred embodi-h ment of the invention the numeral 5 designates a casing the intermediate portion of tight connection is which is enlarged as'illustrated in Figure 1 to provide for free passage of water. The end portions of the body 5 are provided with interiorly threaded attaching portions by' means of which the valve may be located in a water main. Of course the valve may be of any size and the attaching portions 6 are of a diameter to conform tothe diameter of the main in which the valve is located. Also the valve seat8 may be of rubber, brass, lor other material as desired.

The interior of the casing 5 is provided inwardly of the attaching portions 6 with valve seats 8 with which annular yieldable contact members 9 of valves 10 contact to shut off the flow of water through -the valve.v A further object of the invention is to r In carrying out the inventionthe several valvesy 10 are provlded with centrally arranged threads 11 which extend through Y disks 12 held in place by means of nuts 14. y

Figure'2 illustrates that the discs 12 extend beyond an annular iange 16 on the valves 10 .I

and the discs r/est upon the' ange land engages the yieldable valve seat Contact inember 9 tohold the same in place. It will be seen that by the proper adjustment vof' the 4 discs the portion 9 may be compressed and spread to compensate for wear..v

` The rear portions of the valves 10 are prod Y l vided with apertured ears 18 to which operating links 19 are connected by means of pivot bolts 20. The inner .portions of the. v

links 19'areein turn pivotally connected as' indicated at 22 to the lower portion or connecting member 24 of an .adjusting stem 25.l

Itwlll be seen that the connecting member 24 is in the nature of a cup-shapedg'body which receives an annular flange 27 on the lower end of the stem and a sleeve nut 28 isl threaded into the cup-shaped body to engage the'iiange 27 and thereby connect the stern to the body.

Attention lis directed to the fact that the stem 25 is free to rotate with relation to the cup-shaped bod 24so that the stcmcmay be moved up and own by means of the threadi ed connection 29 between the cap 30 and the stem. The cap 30 vis threaded into the top` of the -valve casing 5 and is provided with a stuffing box 32 by means of which a water and the stem.

provided between 'the cap v To guide the several'valves-to'theseats at L the opposite ends of the-casing the valves are provided with oppositely directed ears 36 suitable type.

having transverse slots to' freely receive `trated in Figures 4, 5 and 6 the casing is indicated by the numeral andis provided at its ends with attaching members 71 of any The casing is provided adjacent the attaching members 71 with valve seats 73with which valves 75 of anypconstruction may be engaged to shut olf the fl'o'w f of Water. The inner sides of the valves 75 are provided with a ertured ears 7 6 to which operating links 7 are pivotally connected, as indicated at 78.

rlhe inner ends of the links 77 are pivotally connected to the ears 78 of an attaching member 79 and thev attaching member is formed with a socket for the reception of the enlarged lower end of an adjusting stem 80. It will be seen that the turning of the stem 80 in the closure or`cap`81 will result in the vertical movement of the stem so as to move the links 77 either in or out.

One of the important features of the invention resides in the fact that the upper portions of the valves 75 are provided with T-shaped heads 83 slidable in channel members 74 in the upper wall of the casing. It

is thus seen that' the valves 75 are slidably,

but non-rotatably, mounted within the casing so that the same are maintained in posi- 'tion to engage the valve seats 73. As the links 77 are drawn inwardly and upwardly, the valves, and more particularly the T shaped heads 83 of the same, will ride in the channel members 84 so as to maintain the valves in position to again flatly contact `with thc seats 73 for shutting oft' the flow of water or other liquid.

Also the valves are provided with .pairs of rearwardlyV projecting ears 85 to which links 86 are connected, and the inner ends of the links are connected to eye-bolts or other apertured members 88 carried by the ears 78 so that as the valves. are drawn inwardly they are swung upwardly in the direction of the top of the casing to allow of the free passage of water through the casing. ln other words, the valves swing out of the way of the water or other liquid when .moved inwardly. vOn the outwardmovement of the links 77 the valves will again engage the seats. It is thus seen that a dual connection is provided between the valves 75 and the operat stem and by reason of The clean-out member-50 is in the nature of a plug threaded into'therside of the casing and of suiiicient diameter to afford free access to the interior of the casing.

A valve constructed in accordance with this invention is capable of long and efflcient l'Wear and consequently frequent replacement and interruption in the water service is unnecessary. The large amount .of sand and gravel which ordinarily accumulates in valves of this type will not prevent the complete seating of the several valves and consequently the possibilities of leakage is reduced to a minimum.

The foregoing illustrates that the invention forming the subject-matter of this application is capable of a Wide variety of mechanical expressions and, therefore, such minor changes in arrangement and construction of parts may be made as will remain within the spirit of the invention and the scope of what is claimed.

Having thus described the invention, what is claimed is 1. A valve comprising a casing having valve seats at' its ends, valves co-operable with'the seats means carried by the casing and co-operable with the valves to permit the valves to slide toward and away from the valve seats while preventing Yrotary movement of said valves, links connected to the valves, and an operating stem connected t the links.

2. A valve comprising a casing having its end portions provided with seats, valves adapted to contact with saidseats, links pivotally connected to said valves, a connecting member pivoted to the inner portions of the links, an operating stem connected to said ,connecting member, and .a second set of links connecting the valves to the said connecting member and being joined with the valves below the centers of the same, whereby to swing the valvesnpwardly upon the inward movementof the links.

3. A valve comprising a casing having its end portions provided with seats, valves adapted to contact with said seats, links pivotally connected to said valves, a connecting member pivoted to the inner portions ofthe links, an operating stem connected to said connecting member, a second set of links connecting the valves to the connecting member and being oined with the valves below the centers o the same, whereby to swing the valves upwardly upon the inward movement of. the links, and means slidably and swingingly connecting the upper portions of the valves to the casing.
